He won an Olympic gold medal in London (his home town.)
Both men and women pay attention to the olympics, especially a home Olympics, so he became a huge star off of that.
Then basically he got Eddie Hearn as an agent which helped AstroTurf his popularity even more.
I remember back in 2016 you couldn’t turn on Sky Sports News without seeing an image of Anthony Joshua permanently branded on the side banner.
He’s basically a bodybuilder turned boxer, which is why a lot of women loved him and helped make him even more popular. He was perfect for marketing... as long as he kept winning.
Now he’s been exposed twice, and his career is basically over — thank god
